Odin stages require a physical team (of Bow units if possible) and, most important, some skills.

All the units in this stage have an high MDEF and Odin receives 90% less damage from Fire, Ice, and Darkness (80% less from lightning): units like Pahrl, S'naip and Harold will be of tremendous help, while Zafitte, Gugba and even the C class monsters Blastosaur (Chapter 5-4) and Bomborg (Chapter 8-9) can defuse the bombs spawned by Odin right after he shined for 1 turn and casted Zantetsuso.
